De-aged stories of these fools are my jam. I would read all of them, every single one I can find. There is something about Harry dealing with kid-Draco that melts my heart.
Draco is tutoring 8th year Harry in potions when he makes a mistake and the potion blows over Draco, de-aging him to a 4yo. Draco grows up one year every week until he’s 18yo again. All this time Harry is his guardian and caretaker.
It was adorable and I couldn’t get enough. Some things didn’t make sense, like Lucius and Narcissa not getting his boy but leaving him in Harry’s care. Then the pervert teacher plot line was so unnecessary, it did nothing to the story so I’m not sure why it’s there.
